Homing Direction and +/- XY axis direction

Post by smokey9lives » Wed Nov 20, 2019 8:01 pm

When I first set up the motors in CAMotics the X and Y axis moved away from my limit switches. I could fix this by reversing the motor direction but then, when I should be moving in +XY the CAMotics measures the movement as -XY.

Is there a way to change the homing direction without reversing the motors?

Right now, when looking at the front of the machine, I home the machine to the right rear corner of the bed where my limit switches are. If I then set a G54 (G10 L20 P1) offset at the front left of the bed the CAMotics viewer shows the machine bounding box to the front and left of the G54 coordinate (which is off of the bed and has the +XY in the reverse direction.

Thanks,
Jason

Try reversing one pair on the motor wiring on each motor. This will cause your motors to turn in the opposite direction without checking the 'reverse' box on the motor configuration.
